∙ 15y agoThe question is poorly put. It is chemical reactions that are called 'endothermic' or 'exothermic'. The reaction describing the formation of a given chemical may be either.

∙ 9y agoNo, formation can be endothermic (in that case the decomposition is exothermic)

can you relate endothermic and exothermic reactions to specifically the making and breaking of bonds?
Breaking a chemical bond is endothermic and making a bond is exothermic.
Can you relate exothermic and endothermic reactions to the making and breaking of bonds?
Bond breaking is endothermic, which means it takes energy. An example would be breaking a window. Bond making is exothermic, which means it releases energy. An example would be burning a substance.
What is the role of energy in forming bonds and breaking bonds?
The enthalpy change associated with a reaction = sum of (energies of bonds broken) - sum of (energies of bonds formed). Thus, if this value is net negative, the reaction is exothermic; the products are also more stable than the reactants (lower-energy bonds). A positive enthalpy indicates an endothermic reaction.
Is water evaporating an exothermic process?
The evaporation of water is endothermic. In order for the hydrogen bonds to be broken in water (which is required for water to evaporate), an input of energy is needed. Conversely, the condensation of water vapor is exothermic.
Is Liquid water turning to ice a endothermic or exothermic process?
The process of freezing is an exothermic process. Particles in a liquid have more energy than those in a solid, hence they vibrate / move more. Therefore, to turn a liquid into a solid, energy needs to be taken out of the liquid. This means energy is given off to its surroundings, making it an exothermic process.
Is bond breaking an endothermic or exothermic process?
Breaking bonds produces energy making it an exothermic process.

Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.

How do you predict if a reaction will be exothermic or endothermic?
Although it is hard to predict if a reaction will be exothermic or endothermic, there are many factors that can be considered when trying to determine it. first endothermic reactions usually employ the breaking of strong bonds, and the creation of weak bonds. While exothermic reactions usually break weak bonds and create strong bonds. Sadly these are the only ways to predict if a reaction will be endothermic or exothermic, altough there are other methods that could be used that are much more complex.

Is water dissociation exothermic or endothermic?
It's endothermic as heat is required in order to cleave the bonds.
Reactions that release heat as bonds are broken are called .?
exothermic
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
Exothermic reaction
Is electrolysis of water an example of exothermic process?
Breaking chemical bonds is always endothermic. 463 kJ/mole are required to break O-H bonds. There are two O-H bonds per water molecule, so one mole of water requires 926kJ to break all the bonds. this energy requirement is supplied by the electrical current.
